The cis bond causes a lower melting point and, ostensibly, also the observed beneficial health effects. Unlike other trans fatty acids, it may have beneficial effects on human health. [ 6 ] CLA is conjugated , and in the United States, trans linkages in a conjugated system are not counted as trans fats for the purposes of nutritional ...
Palmitoleic acid has 16 carbons, is found in cod liver oil, sardine oil, and herring oil, and is a cis-9-monounsaturated fatty acid. C 15 H 29 CO 2 H, IUPAC organization name (Z)-hexadec-9-enoic acid, n-7, numerical representation of 16:1, molecular weight 254.41, melting point 5 °C, specific gravity 0.894. CAS Registry Number 373-49-9.
Linoleic acid (LA) is an organic compound with the formula HOOC(CH 2) 7 CH=CHCH 2 CH=CH(CH 2) 4 CH 3. Both alkene groups (−CH=CH−) are cis. It is a fatty acid sometimes denoted 18:2 (n−6) or 18:2 cis-9,12. A linoleate is a salt or ester of this acid. [5] Linoleic acid is a polyunsaturated, omega−6 fatty acid.
The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is a regioisomer of gamma-linolenic acid (GLA), an 18:3 (n−6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds).
It can refer to either of two octadecatrienoic acids (i.e. with an 18-carbon chain and three double bonds, which are found in the cis configuration), or a mixture of the two. Linolenate (in the form of triglyceride esters of linolenic acid) is often found in vegetable oils; traditionally, such fatty acylates are reported as the fatty acids:
These three locants are typically indicated as Δ9c, Δ12c, Δ15c, or cisΔ 9, cisΔ 12, cisΔ 15, or cis-cis-cis-Δ 9,12,15, where c or cis means that the double bonds have a cis configuration. α-Linolenic acid is polyunsaturated (containing more than one double bond) and is also described by a lipid number, 18:3 , meaning that there are 18 ...
DGLA is a carboxylic acid with a 20-carbon chain and three cis double bonds; the first double bond is located at the sixth carbon from the omega end. DGLA is the elongation product of γ-linolenic acid (GLA; 18:3, ω−6). GLA, in turn, is a desaturation product (Delta 6 desaturase) of linoleic acid (18:2, ω−6). DGLA is made in the body by ...
Linolelaidic acid is an omega-6 trans fatty acid (TFA) and is a cis–trans isomer of linoleic acid.It is found in partially hydrogenated vegetable oils. It is a white (or colourless) viscous liquid.
